Precision alloy low expansion alloy 4J36 FeNi36 nickel-iron Nilo 36 invar 36 round bar rod

Invar 36 is an alloy that is 64 percent iron and 36 percent nickel. It is generally thought of as the metal of choice for any type of low expansion application, because it has a very small CTE (coefficient of thermal expansion). The low expansion level associated with Invar 36 makes it perfect for use in precision measuring devices such as laser components, thermostat rods, clocks, and scientific instruments. Invar 36 also maintains its strength in extremely low temperatures, which has made it vital in the transportation of certain liquid gasses. In many environments, Invar 36 actually possesses thermal characteristics that are equivalent to glass, which has caused people to use the alloy in a variety of optical instruments.
